12 Claims.

one or more merchandise-supporting and retaining members which the usermay insert into the box body for retaining the merchandise in properfixed position within the container body.

In accordance with my invention, a box body is provided which may beformed iroma single blank of paperboard material which may be cut 15substantially rectangular in shape with a minimum of waste of paperboardmaterial, which body-forming blank may be cut and scored preparatory toassembly on an automatic cutting and scoring machine at a highproduction rate. The box body generally comprises a bottom wall paneland enclosing side and end wall panels hinged thereto, the enclosingpanels being suitably connected at the corners by means of se curingflaps or edging strips. The opposite, end walls are each provided with afold or score line extending diagonally from one lower corner of the boxbody upwardly in a straight line to the upper edge of the end wallpanel. One of the side wall panels is provided with a pair of diagonallyextending and converging score lines which extend from the'oppositelower corners of the box upwardly to the upper edge of the side wallpanel. As thus formed, the scored side wall panel is divided into acentral collapsing section adapted to be folded inwardly so as tooverlie the bottom wall panel and end sections folded inwardly so as tooverlie the central collapsing section of the side wall section. Thediagonally extending fold line traversing each end wall panel divideseach end wall panel into two collapsing sections, one of which sectionsmay be collapsed inwardly to overlie the inside face of the adjacent endsection forming a part of the scored side wall panel, and the other end45 wall section being then folded so as to overlie its companion endwall section, thus permitting the opposite unscored side wall section tobe folded downwardly so as to overlie the adjacent end wall sections towhich it is connected, pro- 50 vlding a substantially flat collapsed boxbody. A plurality of such collapsed box bodies may be stacked togetherso as to occupy a minimum oi space during shipment and storage.

When the user desires to place merchandise 55 in the box, the same canbe erected into contamer-forming position by merely erecting the sidewall panels into a position substantially at right angles to the bottomwall panels. That side wall panel which is provided with the convergingand diagonally extending fold lines, is 5 provided with a lip or flapportion hinged to the upper edge thereof which may be turned inwardlyafter the merchandise has been inserted into the box body, which lipportion serves thereafter as a bracing and reeniorcing strut which 10preventsinward collapse of the side and end wall panels of the box. Tofurther reenforce and strengthen the construction, a similar lip portionmay be hingedly connected to the upper edge of the other side wall paneland also to 15 the upper edge of each of the scored end wall panels.

If the merchandise is of a fragile nature so as to be susceptible todamage in shipment, I provide one or more merchandise-containing and 20supporting insert members which may be telescoped into the erected boxbody. Each insert is provided with a merchandise-supporting platformhaving an area substantially co-extensive with the interiorcross-sectional area of the box 25 body. Each platform is provided withdownwardly extending supporting flanges which may rest upon the bottomwall panel of the box so as to maintain the platform in the properspaced relation to the bottom wall panel. Each plat- 30 form may have amerchandise-receiving opening cut therein, the peripheral edges of saidopening being shaped to substantially conform to the contour of themerchandise, thus retaining the merchandise out of contact with the sideand as end wall panels of the box body and also, if desired, out ofcontact with the bottom wall panel and the cover panel of the box. Thecover panel may be hingedly connected to one of the platforms by meansof a spacing section which lies adjacent the inside face of one of theenclosing walls of the box. When the cover panel is in closed positionthe facing section is maintained in close abutting relation with theadjacent enclosing panel, thus further reenforcing and 45 strengtheningthe box-enclosing walls against inward collapse. The cover panel may beprovided with flanges which telescope over the exterior surface of oneor more of the enclosing panels of the box body or it may be providedwith one or more insertion flaps hinged thereto which may be insertedinto the box interior.

An object of this invention is to provide a highly serviceable cartonfor the packaging of various articles of merchandise which can be lwalls thereof.

Another object of thisinvention iato provide presents a box body whichquickly erected into abox body which can be economically constructed andmanufactured froma single blank of automatic machinery at low cost,which box body is provided with means to effect substantially flatcollapse of the enclosing. side walls thereof L for shipment and storagepurposes and which thereafter may be erected by the user as needed toreceive the merchandise therein, means being provided to retain theenclosing sidewalls in rigid erect merchandise-enclosing and protectingto be inserted into a box body,

position. v

Another object of this invention is to provide a shipping cartoncomprising a box body having associated therewith amerchandise-retaining and supporting insert so constructed as to retainthe merchandise in tive to the enclosing side walls of the box body,thus to protect the merchandise against damage during shipment.

Still, another object of this invention is to provide amerchandise-supporting member adapted comprises a merchandise-supportingplatform having merchandise-engaging means to retain the merchandise infixed position within the box body, said merchandise-supporting memberhaving a box cover formed as an integral part thereofo I Other objectsof this invention will becom apparent as the disclosure proceeds.Various other features and advantages of the invention will be apparentfrom the following particular description and from an inspection of theaccompanying drawings. Although the novel features which are believedto-be characteristic of this invention will be particularly pointed outin the claims appended hereto, the invention itself, as to its objectsand advantages, and the manner in which it may be carried out, may bebetter understood by referring tothe following description taken inconnection with the accompanying drawings forming a partthereof, inwhich:

Fig. 9 is a perspective viewoi the assembled box with themerchandise-supporting inserts positioned therein, this view showing thecover' arr ed in partially closed position; and

Fig. 10 is a vertical or tageously formed from a single blank A ofpaperboard.material, as shown in Fig. 1. It will be noted that the blankA is substantially rectangular in outline To permit substantially flatcollapse of the box when assembled, a score line 1 extends across eachof the end wall panels 3, dividing each panel into two collapsingsections 30. and 3b. Each score line 1 extends from the meeting point ofthe score lines 6 and 5 to the top edge of the end wall panel 3, to formthe generally triangular-shaped collapsing sections 3a and to. One ofthe side wall panels 4 is provided with a pair of diagonally extendingscore Points of the score lines 5 and 6 and extending across the sidewall panel inan inwardly converging direction to the top edge of theside wall panell. 8 divide the side wall panel 4 into a centralcollapsing section 4:: and two end collapsing sections lb.

Side wall panel 2 is provided with a securing flap 9 hinged to each endthereof along the score line l0. Asecuring flap H is hinged to the sideedge of each end collapsing section lb of the front The side wall panel4 is also portion l5 which extends sub stan-tially the full lengththereof and is hinged L thereto along the score line l6. It will benoted by referring more particularly to Fig. 1 that 1, by an automaticcutting and scoring machine without-hand labor.

In assembling the blank A into box form, a suitable glue or adhesive 9is applied to the inside face of the end wall panels 3, which operationcan be performed automatically by a spot gluing machine of well-knownconstruction.- This same machine operates to raise the side wall panels2 and 4 into a position substantially at right angles to the bottom wallpanel I, then operates to fold the securing ilaps 9 and II inwardly, asshown in Fig. 3, then operates to raise the end wall panels 3 into aposition substantially at right angles to the bottom wall panel I, andfinally presses the securing flaps 9 and II into adhesive contact withthe inside face of the adjacent end wall panels 3. The box as thusformed and ejected I from the machine isfully assembled with the sideand end wall panels in. upstanding position.

It will be noted that the glued area 9 applied to the end wall panels 3so as to secure the' securing flaps II to the adjacent end panelsections 3a only, and it will be particularly noted that the securingflaps II are not to be adhesively secured to the end panel sections 3b,Likewise the securingfiaps 9 hinged to the side wall panel 2 areadhesively secured to the end wall sections 31) only, and are not to besecured to the end wall sections 3a. To prevent the securing flaps 9from being secured to the end wall sections 3a, the lower edge 9athereof may be so cut as to coincide with the diagonal score lines I ofthe end wall panel, when the box body is erected, al-

, though it will be appreciated that the lower edge score line 1.

hinged to the side wall panel 4 may be of such mi'rably adapted for suchcollapse.

9b can extend beyond and overlap the end wall section 3 if care is takenin applying the adhesive to the securing flaps 9 or to the end wallsections 3b to which they will be secured, sothat the edge of this gluesarea terminates at the Likewise, the securing flaps II area as tooverlap the end wall section 3b if the adhesive is so applied to thesecuring flaps II or the adjacent end wall sections 3a so that theadhesive intended to secure the securing flaps II to the end wallsection 3 does not overlap or extend beyond the score line I. Thiscaution must be observed if the box is to collapse in a satisfactorymanner.

After the box or carton has been assembled by the box manufacturer, itis shipped to the user in the collapsed position shown in Fig. 6, andthe user packs the merchandise therein as needed. Since the erected boxwould occupy substantial space in shipment and storage, it is highlydesirable that it be so constructed that it may be shipped. and storedby the user in collapsed substantially fiat position so as to occupy aminimum of space. My improved box is ad- In collapsing the assembledbox, the box manufacturer folds the central side wall section 4 into aposition to substantially overlie the inside face of the bottom wallpanel I, as shown in Fig. 5. The end sections 4b of the side wall panel4 will then fold so as to overlie the central section 4a; each end wallsection 3a will foid so as to overlie the adjacent end section 4b; theend wall sections 3!: will fold so as to overlie the end wall sections30, and finally the side wall panel 2 will collapse so as to 'overliethe end wall sections 311, so that each box may be completely collapsedinto substantially flat form, as shown in Fig. 6. In the collapsingoperation it will be noted that the central lip section I50. willoverlie the inside face of the bottom wall panel I, and that the end lipboxes may be stacked together and thereafter bundled, wrapped, or boxedfor shipment. It will be appreciated that a large number of collapsedboxes may thus be packed for shipping and storage in a relativelylimited space.

When the user desires to pack an article of merchandise M within thebox, the box is quickly erected by lifting the side wall panel 2 into aposition substantially at right angles to the bottom wall panel I andthen lifting the central section 4a of the side wall panel 4substantially at right angles to the bottom wall panel I. This lastoperation automatically brings the end sections 4b of the side wallpanel 4 and the end wall sections 3a and 3b of the end wall panels 3into a position substantially at right angles to the bottom wall panelI, providing an open, erected, four-side box which receives themerchandise. It will be noted by referring to Fig. 4 that a cornerportion II' of each unscored securing flap I I extends over the foldline I and overlaps a portion of the adjacent end wall section 3b. Thisarrangement materially braces and strengthens the end wall panelsagainst outward collapse when the box is erected.

After the merchandise M has been packaged therein, the box may bemaintained in rigid erect position by folding the lip portion I5inwardly substantially at right angles to theside wall panel 4. The lipportion I5 serves to brace and stiffen the side wall panel 4 so that thediagonally extending score lines 8 therein are ineffective to effectcollapse of the box. A similar stifiening lip portion I3 provided on theside wall panel 2 is also turned inwardly substantially at right anglesto the side wall panel 2 after the merchandise has been packed in thebox. To further stiffen the construction, similar lip portions I'I maybe hinged along the score-line I8 to the upper edge of each end wallpanel 3, as shown in dotted lines in Fig.7. If lip portions H areprovided on the end wall panels 3, the diagonally extending score line Icontinues through the lip portions Il dividing the same into lipsections Na and "D. As thus constructed the lip portions I1 do notinterfere with the full and satisfactory collapse of the. box structure.It will be appreciated that normally the lip portion I5 when inturnedserves to maintain both end wall panels 3 as well as the side wallpanels 2 and 4 in erect container-forming position, and the lip portionsII hinged to the end wall panels 3 need only be provided if additionalstiffness and strength is desired.

In the packaging of certain forms ofmerchandise it is desirable that themerchandise be held in fixed position within the box body so that itwill not be damaged during shipment. One or more merchandise-retaininginserts may be positioned within the box body to retain the merchandisetherein in fixed position. A cover for the box may also be formed as apart of one of the merchandise retaining inserts, whichmerchandise-retaining insert and cover may all be chandise-supportingplatform formed from a single blank B of paperboard material, asillustrated more particularly in Fig. 2. This merchandise-retaininginsert and cover as sembly comprises a platform 2| having an areasubstantially equal to the interior cross sectional area of the boxbody. The platform 2| is provided with spacing flanges 26 hinged to theside edges thereof along the score lines 21. The spacing flanges 26 areof such height as to rest upon the bottom wall panel I of the box, asshown in Fig. 10, so as to flrmly support the platform 2| at the properelevation within the box interior.

An end spacing flange 28 equal in depth to the side spacing flanges 26and hinged to the platalong the score line 24 and the cover panel 23 is'hinged to the spacing section 22 along the score line 25. An insert flap38 may be hinged to the other end of the cover panel 23 along the scoreline 3|.

A second merchandise-retaining and supporting insert 0 may be positionedwithin thebox if the merchandise so requires. This insert C may beformed from a single blank of paperboard material, as shown in Fig. 3,and comprises amer- 46 having side flanges 4| hinged thereto along thescore lines 42 and end flanges 43 hinged thereto along the score Y lines44. The side flanges 4| and the end flanges 43 are generally of lessdepth than the side flanges 26 and end flange 28 of the insert B, sothat when positioned in the box, as shown in Fig. 10, platform 40 willbe spaced from the platform 2| the desired distance to properly supportthe merchandise M. The platform 40 is provided with one or more openings0' and 0" so shaped as to snugly receive that portion of the merchandisewhich projects therethrough. It is appreciated that one or more openingsmay be provided as the shape of the merchandise requires. As is shown inFigs. 3 and 10 for purpose of illustration only, the platform 48 isprovided with an opening 0 having a peripheral edge portion 40'conforming to the contour of the adjacent section of the merchandise,and another opening 0" having a peripheral edge 46" so shaped as toconform to another. section of the merchandise. The flanges 4| and 43 ofthe platform C are designed to rest upon the bottom wall panel I of thebox.

In assembling the merchandise-retaining insert formed from the blank Binto the erected box, the side spacing flanges 26 and the end spacingflange 28 are bent into a position substantially at right angles to theplatform 2| and when in this position the spacing flanges 26and 28 andthe platform 2| are telescoped into the box, as indicated in Figs. 7 and8 to surround the insert C, if one is used. It will be noted that theplatform 2| presents an area substantially equal to the interior area ofthe erected box, so that the side spacing flanges 26 lie rather snuglyagainst theinside face of the side wall panel 2 and 4 respectively, andthe end spacing flange 28 lies rather snugly against the inside face ofthe adjacent securing flaps 9 and II. The cover panel spacing section 22will then lie snugly against the inside face of the securing flaps 8 andII at the other end of the box, the spacing section 22 being of suchtype as to extend from the platform 2| substantially to the 'top edge ofthe adjacent end wall panel 3.

The merchandise M is then positioned within the box and drops into theopening 0 provided in the platform 2|. The peripheral edge 2|a of theopening 0 may be so shaped as to either snugly or substantially conformto the regular or irregular. contour of the merchandise M, and theopening 0 in the platform 2| may be such size to retain the merchandiseM in suspended position and out of contact with not only the bottom 1wall panel I butalso the side wall panels 2 and 4 and the end wallpanels 3 of the box, as indicated in Fig. 10. It will be appreciatedthat the merchandise M may be held in suspended position by the platform2| by so cutting the opening 0 so that the peripheral edges 2|a thereofengage the merchandise or the wrapping in which the merchandise ispacked when partially inserted the required distance into the opening 0.By slightly enlarging the opening 0 the merchandise M may be permittedtolie against the bottom wall panel |,'theplatform 2| then serving toretain the merchandise M and its wrapping spaced from the side wallpanels 2 and 4 and the end wall panels 3 only. Thus by making theopening 0 in the platform 2| of the proper size and shape,

the merchandise M may either be held completely suspended by theplatform 2| away from all of the surrounding bottom, side and end wallsof the box, or it may be held spaced from only the side and end wallpanels of the box as the nature and shape of the merchandise requires.

The platform 48 is slightly smaller than the interior cross-sectionalarea of the box, so that the side flanges 26 and the end flange 28 ofthe insert B will seat over the adjacent side flanges 4| in the adjacentend flange 43 of the platform 0, as clearly shown in Fig. 10. Thefrictional contact between these parts retains the platform 26 and 40 ofthe inserts B and C respectively in the properposition- It isappreciated that one or more inserts similar to the insert C may bepositioned within the box as packing conditions require, in which eventthe side flanges 26 and the end flange 28 of the insert B are madedeeper so as to raise the platform 2| thereof closer to the cover panel23. Under certain conditions the insert C may be entirely eliminated andonly the insert B used.

When the merchandise M has been properly packed within the box,. thecover panel 23 is swung into position so as to cover the top of the boxand the insert flap 30 attached thereto is inserted into the box so asto snugly lie against the inside face of theadjacent securing flaps 8and I, as shown in 'Fig. 10. If desired, the securing flap 36 may be ofsuch height as to rest against the platform 2|, so as to maintain thecover panel 23 in fixed spaced relation to the platform 2| and preventthe cover panel 23 at the free end thereof from being telescoped intothe box. Thus both the spacing section 22 and the insert flap 30 may beused to retain the cover panel 23 in proper box-covering position. Thecover panel 23 is further held in fixed spaced relation to the platform2| by the inturned lip portions I3 and 5 which it overlies.

It will also be appreciated that the cover panel 23 may be provided withside flanges 32, as shown in dotted lines in Fig. 7, and an end flange33, as shown in Fig. 7, which may be suitably connected together as by asecuring tab 34,,or an i by the cover panel 33 edging strip as shown indotted line in Fig. 6, in which event the cover panel 23 may be made ofsuch size as to overlie the top edges of one of the end wall panels 3and the side wall panels 2 and 4 with the side flanges 32 snuglytelescoping over the outside face of the adjacent side wall panels 2 and4 and the end wall panel 3|. It will thus be appreciated that the boxcover may either be made as shown in full line in Fig. '7 or it may beprovided with side flanges 32 and an end flange 33 as shown in dottedlines in Fig. '1. q

It will be appreciated that the spacing section 22 when in positionwithin the box braces and reenforces the adjacent end wall panel 3 as toprevent inward collapse thereof. By thus bracing one of the end wallpanels 3 against inward collapse, it will be appreciated that inwardcollapse of the other end wall panel and the side wall panels 4 and 2 isalso prevented. The spacing section 22 is prevented from inward collapsewhich acts as a strut extending between the end wall panels 3.

It will be further appreciated that the merchandise-supporting platform2|, snugly fitting within the box interior, also braces the side and endwall panels so as to maintain them in erect container forming positionand prevents inward collapse of the side and end wall panels, furtheraugmenting the stiffening effect of the inturned lip portion l5 and thespacing section 22 braced and stiffened by the cover panel 23.

The shipping box herein disclosed may be used with or without themerchandise-containing insert. The box can be economically formed from asingle blank of paperboard substantially without waste ofpaperboardmaterial and can be economically produced and assembled byautomatic machinery at a rapid production rate. The box is possessed ofthe advantage of being collapsible into substantially flat position soas to effect substantial economies in shipping and storage prior to usethereof. The box may be quickly erected by the user by the simplemanipulation of rais-- ing the side wall panels 2 and 4, whichautomatically brings the end wall panels 2 and 3 into erectcontainer-forming position. The box is adequately braced and stiffenedby bending the lip portions l3and l5 inwardly sothat the side and endwall panels are maintained in erect, rigid container-forming position.Further bracing of the end wall panels may be obtained by also providingeach end wall panel 3 with an inturned lip portion H as illustrated indotted lines in Fig. 8. A suitable cover may be provided for the box,which cover may be constructed to telescope over the side and end wallpaneis,-if desired.

Where the nature of the goods to be packed is such as to make itdesirable toretain the same in fixed or suspended position therein, themerchandisc-containing insert having the cover panel associatedtherewith is employed. The merchandise M- may be so arranged as to beheld in suspended position by the platforms 2| and 40, as shown in Fig.10 and spaced from the bottom wall I and the top wall panel 23. Thusdelicate merchandise is protected and cushioned against shock deliveredto the bottom and cover wall panels as well as the side and end wallpanels. My improved box and merchandise insert assembly may be made ofany desired size for the packaging of numerous relatively fragile anddelicate articles of merchandise, such as toys made from plastics,edible candy, or other material, as well as numerous other articles ofmerchandise which are relatively fragile and must be carefully packedand cushioned within the container. Actual test have demonstrated thatfragile articles may be packed and shipped in my improved box assemblywith little or no breakage resulting and with greatly less breakage thanis occasioned when similar fragile merchandise is packed in containersas heretofore constructed. The flexible plat forms 2| and 40 arerelatively resilient and gives when exterior strain is imposed upon thewalls of the box, and, further, the merchandise-supporting platform willshift and adjust itself to external pressure applied to the box, so asto protect the delicate merchandise therein against damage. The box andits merchandise-retaining insert can be easily and quickly assembled andpacked and since the cover panel is attached directly to the insert,time is saved in applying the cover to the box. It will be appreciatedthat the inserts B and C may be used for boxes which are not madecollapsible, although the insert B is particularly adapted for use inboxes of the V collapsible type, since such boxes are rather bulky and aconsiderable saving in shipment and storage costs can be realized bymaking the box collapsible.
